ČSN EN 17845   (728022) Stavební výrobky - Posouzení uvolňování nebezpečných látek - Stanovení reziduí biocidů pomocí kapalinové chromatografie s hmotnostní spektrometrickou detekcí (LC-MS/MS)

Anotace textu normy ČSN EN 17845   (728022)

This document describes a method for the determination of the content of biocides in construction products, (either finished (dried) or in a ready-to-use state) and in eluates thereof, using liquid chromatography and tandem mass spectrometric detection (LC-MS/MS).

For content analysis liquid chromatography with UV-detection can also be used, if sufficient sensitivity and selectivity is ensured (see Annex A (normative)).

The method in this document is validated for the product types listed in Annex D (informative). For eluate analysis quantification limits of 0,1 µg/l can be achieved.
